According to the BGP routing table, the next hop address of the route destined for 172.16.1.0/24
is 200.1.1.2 and service flow is transmitted on the active link Switch A → Switch B.
Step 4 Configure BFD, and set the interval for transmitting BFD packets, the interval for receiving BFD
packets, and the local detection multiplier.
# Enable BFD on Switch A. Set the minimum intervals for transmitting and receiving BFD
packets to 100 ms and the local detection multiplier to 4.
